Overview
The Bourns MH3261-471Y is a high current chip ferrite bead designed for surface mount applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 40 mOhms. The operating temperature range spans from -55 C to +125 C.
Feature Summary
- High current capability suitable for power and signal line filtering
- Low DC resistance minimizes power losses in the circuit
- Compact 1206 footprint enables dense layout designs
Applications
- Power supply output filtering
- Signal line noise suppression
- EMI suppression in industrial control panels
Procurement Notes
Verify availability status as this part may be discontinued or obsolete. Confirm exact impedance and current ratings against the official datasheet before integration. Check for RoHS compliance details if required by specific regulatory standards. Ensure the SMD/SMT termination type matches the PCB fabrication process.
Selection Notes
Select this component when high current handling is required alongside significant impedance at 100 MHz. The low DCR characteristic makes it efficient for power lines where voltage drop must be minimized. The 1206 size offers a balance between current capacity and board space constraints compared to smaller packages.
Part Context
This component belongs to the MH3261-T series of high current chip ferrite beads manufactured by Bourns. The series is characterized by compact size, low profile, and low DCR capabilities. These beads are engineered to suppress electromagnetic interference in demanding electronic environments while maintaining structural integrity under high current loads.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if sourcing alternatives due to obsolescence.
